Database

We will use the database, whose schema and data import commands are given here:

You can import this database by copy pasting the comands on that page.

Note: When using the CLI, please modify any multi-line query in the documenation to be in a single line.

LIMIT

LIMIT controls the number of tuples returned from a query. It is often used within in an ORDER BY clause to fetch the top k tuples from the query result. Note: LIMIT accepts any expression that can be evaluated to an integer.

For example, the following query returns the top three oldest users. Query:

MATCH (u:User)
RETURN u.name
ORDER BY u.age DESC
LIMIT 3;

Result:

-----------
| Zhang   |
-----------
| Karissa |
-----------
| Adam    |
-----------

If you omit the ORDER BY, you would get some k tuples in a LIMIT k query but you have no guarantee about which ones will be selected.
